Electromagnetic chucks

In some cases it may be of brass The pole structure is replaced with an epoxy resin. Electromagnetic chucks are supplied with direct current, the voltage is 110 VDC. Therefore, these types require special power supplies, in addition to the power-hatted as Demagnetizer - when switched off, the electromagnet starts demagnetizer cycle, which minimizes the residual magnetism in the workpiece. Nowadays, modern resources for electromagnetic chucks have all its functions controlled by a microprocessor and, moreover, they can be degaussing program set up for a variety of specific materials (construction steel, alloy steel, tool steel, etc.). The biggest advantage compared to permanent electromagnetic chuck is therefore their ability to complete or at least partial removal of residual magnetism from the workpiece.
